User manual

don’t have the SSID made available but have the network listed
as a “hidden network” on some devices. This is something you
can do in your router’s or access point’s Web-based management
interface
When your network client devices are active in your wireless
network and are “talking” to your wireless access point or router,
they don’t broadcast an SSID or other beacon because they have
“latched on” to that access point or router. This data will usually
be encrypeted as part of the WPA security protocols that should
be in place on your private wireless network.
Conclusion
Once you know how the Wi-Fi network works, you should then
know that asite-survey operation should not gather the actual
data that is moved across the network.

The HTML5 vs Flash debate
11/05/2010 09:13
The computer press have been running articles regarding the use
of Flash or HTML5in highly-interactive Web sites such as
videosites.
It has started off with Apple wanting to move iPhone and iPad
towards HTML5 /H264 video by proscribing Flash runtime
engines from these platforms and forcing developers to move to
the HTML5 /H264 platform. This caused Google to write
YouTube client-side apps for these platforms and develop an
HTML5 site. Then Microsoft and others worked towards
implementing HTML5in their next browser issue, with some
browsers being equipped with HTML5 interpreters.
The debate about HTML5 vs Flash has been more “video-centric”
because Adobe Flash was mainly used by YouTube to display the
many videos hosted on thatsite.
It is worth noting that the FLV files used in YouTube and similar
Flash applications are container files with the video and audio
encoded using the H.263 video codec. The HTML5-based video
applications will use FLV, MOV or AVI container files with H.264
video codecs which are becoming the standard for
high-resolution video.
Applications beyond video
Adobe Flash has been used for applications beyond video.
Primarily it has been used for high-interactivity applications like
games such as Farmville on Facebook or the casual games on
MiniClip because it offers aquick-response user interface and
easy development that these applications needed. Here, it has
offered a “write-once run-anywhere” platform for these
Web-centric applications with plenty of
“rapid-application-development” tools.
It is also worth knowing that most of these games refer to
back-end databases and /or “client-local” cookie files to
persistently store game-state and other user-generated data.
These programs will then have to work with the different data
stores as they areused.
Web-based runtime environments for partially-linked
programs
HTML5 has avariety of inherent elements that allow for
vector-graphics and interactivity for highly-interactive
applications. It also may be of benefit to open-source software
developers and Linux advocates/
But there are some developers, most notably games developers,
who want to keep their source-code closed in order to control
reuse of that code. These developers also want to provide
programs in amanner where the target machine doesn’t have to
interpret or compile code before it is of use, which will benefit
high-interactivity applications where quick response is desired.
These developers typically want to provide these programs as
either an executable file or a “p-code” (partially-linked) program
file which is run by an interpreter or just-in-time compiler
program, known as aruntime module, that works with these files
on the target platform. At the moment, there isn’t amechanism
for delivering acompiled HTML5 file in a “write once, run
anywhere” manner.
Java
An interactive-applications developer could work with the latest
version of Java to develop these kind of applications in a
“write-once run-anywhere” platform. This platform is natively
supported by the Blu-Ray Disc system as part of providing
interactive video from discs and/or the Internet through that
system. It could then lead to someone writing agames disc that
runs classic games types on any old Blu-Ray Disc player without
the player being agames console.
The main issue with this is that not all platforms, especially
tablet and handheld platforms, support Java natively. As well,
desktop support for Java may require the Java runtime software
to be downloaded separately fromSun.
